WebHowever, interphase does not describe a cell that is merely resting; rather, the cell is living and preparing for later cell division, so the name was changed. A common misconception is that interphase is the first stage of mitosis, but since mitosis is the division of the nucleus, prophase is actually the first stage. WebThe three stages of interphase are called G 1, S, and G 2. G 1 Phase (First Gap) The first stage of interphase is called the G 1 phase (first gap) because, from a microscopic aspect, little change is visible.
